Simple rails example fails

Hi,

I am a Rails newb. Am using an online tutorial to learn the rails.

http://www.visionmasterdesigns.com/2008/08/tutorial-create-blog-using-ruby-on-rails-2-relationship/2/

It is about creating a simple blog. I have generated the scaffolding for the categories table and the posts table following the instructions. I expect posts to infer that category_id is a foreign key to the categories table and to therefore generate a dropdown list. However I am getting an textfield when i hit the new post page. (category_id is assigned 0 whenever I create a new post). I am very much a newb at rails, am I missing something obvious here?

Hi There,

Not familiar with this tutorial ( there is a fair bit of criticism in the comments ! )

But have you followed the code in the view to add the comments drop down ? ( third page of tutorial ) In your post you are sort of suggesting this should happen automatically because of the relationship, but this is not the case.
